SPECIFICATION forming part of Letters Patent No. 579,850, dated March30, 1897.

Application filed November 17, 1896. Serial No. 612,469. (No model.)Patented in Belgium November 30,

To all whom it may concern.-

Be it known that I, ANTON UHLMANN, a subject of the King of Saxony,residing at Olbernhau, Saxony, Germany, have invented certain new anduseful Improvements in or Relating to Ink-D1-iers, (for which I haveobtained Letters Patent in Belgium, No. 124,535, dated November 30,1896,) of which the following is a specification.

The object of the present invention is a blottin g-pad having tworollers, to which the ends of a strip of blotting-paper are seoured'insuch manner that as the strip, guided over a convex surface, is used upor rendered useless it is unwound from one roller and wound up on theother. The article is made so as to enable it to be easily taken topieces in order to replace the blotting-paper, which will be sold readywound on rollers having central spindles, the apparatus consisting of asfew parts as possible, which is effected by causing one part to servefor several different purposes, as, for instance, the sides in which thespindles of the rollers are supported act also as a brake for saidrollers, and with their hooked ends serve as stops or abutments.

In the following description reference is made to the accompanyingdrawings, in which Figure 1 is a side elevation of the article. Fig. 2is a plan in which the central portion of the upper part is broken awayin order to show the parts arranged under it. Fig. 3 is a view of a rollof blotting-paper with roller and spindle.

The blotting-pad consists, first, of an upper part A and a lower part B.The latter consists of a convex spring or elastic piece of sheet metal.The former can also be apiece of sheet metal, but may be of differentmaterial. A is provided with a knob A, which serves as a handle, and ithas at its four corners projections or eyes a, which slightly projectfrom the transverse edges, Fig. 2, and surround the tubular edges 6 ofthe plate B, which edges extend the whole width of the lower part B andover which edges the strip of blottingpaper is guided when unwound orwound up on the rollers. Through a and b on each side is passed a pin 0,whereby the upper andlower part are connected to each other so that theymay be easily disconnected, and, as will be hereinafter shown, theseparts are connected with the sides of the article. The lower surface of13, over which passes the strip of blottin g-paper, is preferablycovered with a layer B of some soft material, such, for instance, asfelt.

D D are two sides or cheeks of springy sheet metal, which in consequenceof their elasticity always have a tendency to bend inward, as indicatedin Fig. 2. In the ends of D D are holes through which the pins 0 0 pass.The sides are arranged on the pins between a and b, and owing to theirelasticity they press against a and against the rollers. Over the pins 0c the sides or cheeks are formed into hooks d d, against which bear thetransverse edges of the upper part A when pressure is exercised on A.Thus the strain of the pressure exercised when using the article istaken off the weak lugs a, and A is protected against deformation andinjury.

In D D are supported the spindles e e, on which are secured rollers E E,preferably made of wood. Along strip of blotting-paper F is glued fastat its end and wound on one of the rollers, say on E. Such a rollerprovided with blotting-paper is shown in Fig. 3. On the free end of thestrip F may also be glued a (empty) roller with spindle. If this is notthe case, the free end of the strip F may be secured on the secondroller E after having been properly stretched in place.

It is clear that in tending to bend inward the sides or cheeks D D mustexercise a pressure on the ends of the rollers E E, which pressure actsas a brake, that is to say, makes the rotation of the rollers moredifficult. Thus the blotting-paper on B is always maintained stretched,while on the other hand the braking action is not strong enough toprevent rotation of the rollers by hand. The latter is effected by meansof suitable handles which are mounted on the ends of the spindles e 6 soas to be easily removable. For instance, they can be thumb-nuts g g,screwed on the screw-threaded portion g of the spindles, Fig. 3.According to Fig. 2 the handles are arranged on the opposite sides ofthe pad. They may, however, be arranged on the same side. The spindlesmay also be provided with screw-threaded portions on both ends. It isimportant to provide each spindle with a handle, although whenever oneroller is rotated in the direction of winding up the other is alsocaused to rotate in the direction of unwinding. If the roller E, Fig. 1,which already is almost fully covered with woundup blotting-paper, wereto be rotated farther in the direction of winding up, then in consequence of the great ratio between the large circumference of theroller E and the small circumference of E the paper would be eX- posedto a great strain and might break. The nearly-empty roller E istherefore rotated first by means of its handle 9 in the direction ofunwinding and then the winding up 011 the full roller E is effected.Moreover, when there are two handles it is possible to wind up on eitherroller, as desired.

For the purpose of putting in a new roller or rollers of blotting-paperthe article is taken to pieces, the handles g g are unscrewed and thepins 0 c are withdrawn, the rollers (or one, the full one) are taken outand the new roller or rollers put in. From the full roller the paper isguided, after the pad has been again put together and the handlesscrewed on, over I) and B, Fig. 1, then over the other edge 1) to theempty roller. Then the paper arranged on 13' is saturated with inlgthestrip F can be wound up 011 E. A strip which has once passed over theblotting-pad can he turned over, so as to use its other surface beforeit is thrown away.

1. A blotting-pad device consisting of a convex under support for theblotting-paper, and an upper plate, connected together by spindlespassed through their tubular edges, elastic side plates also secured onsaid spindles and provided with hooks or notches at their.

ends which serve as abutnients for the upper pressure-plate, said sideplates supporting and acting as a brake upon two rollers for theblotting-paper, which is passed from one roller around the outer side ofthe under plate and thence to the other roller, said rollers beingoperated by handles iittin g the spindles of the rollers.

2. Ablott-ing-pad device consisting of a convex support B, upper plateA, tubular edges 1) and a of these plates, spindles 0, side springplatesD, rollers E E, spindles c c, and handles g g substantially asdescribed.

3. In a blotting-pad the combination with the upper and lower plates,the pins for eonneeting said parts together and the side plates carriedby said pins provided with notches or hooks at their ends against whichthe edge of the upper plate bears when pressure is applied thereto, asand for the purpose set forth.

In testimony whereof I have hereto set my hand in the presence of thetwo subscribing witnesses.

ANTON UlllAlANN.
